The 2.17 series release notes contain important changes in this release series.

Security Fixes

• Packages have been updated to the latest security versions.

Bug Fixes

• Graphs for some metrics in the Management Console 'Monitor' page were displaying data in the opposite ordering than expected.
• Backups of GitHub Enterprise Server clusters could intermittently fail due to duplicated Gist repository references.
• Transient, non-fatal errors returned from external LDAP servers during team synchronization operations could cause the incorrect removal of team members.

Changes

• Background job queues have been re-ordered to reduce the chances of user-visible jobs being delayed on very busy instances.

Known Issues

• On a freshly set up GitHub Enterprise Server without any users, an attacker could create the first admin user.
• Custom firewall rules aren't maintained during an upgrade.
• Subversion (SVN) checkout may timeout while the repository data cache is being built. In most cases, subsequent svn checkout attempts will succeed.
• Git LFS tracked files uploaded through the web interface are incorrectly added directly to the repository.
• Issues cannot be closed if they contain a permalink to a blob in the same repository where the file path is longer than 255 characters.
• Lines in gists are not selectable.
• The Let's Encrypt certificate registration feature consistently fails following an update to the external API.
• When "Users can search GitHub.com" is enabled with GitHub Connect, issues in private and internal repositories are not included in GitHub.com search results.

Thanks!
